A coumarin-anthracene-based chemodosimeter for the selective detection of arginine
This work presents a coumarin-anthracene-based chemodosimeter L for the selective detection of Arginine (Arg) via hydrolysis of the imine bond of the Schiff base L. Significant changes in the emission and absorption spectra of L were observed during the detection of Arg. Chemodosimeter L displayed an impressive detection limit of 0.46 μM for Arg by the emission spectral titrations. A combination of UV-Vis, emission, and mass spectral studies, as well as excited-state lifetime measurements, and quantum yield calculations illustrated Arg-assisted dosimetry of L. The sensing of Arg by L was employed in cell imaging and for the colorimetric detection and paper test strip-based practical detection methods.
Graphical abstract
This work presents a chemodosimeter L based on a coumarin-anthracene platform for the selective detection of amino acid arginine.
期刊介绍：
Journal of Chemical Sciences is a monthly journal published by the Indian Academy of Sciences. It formed part of the original Proceedings of the Indian Academy of Sciences – Part A, started by the Nobel Laureate Prof C V Raman in 1934, that was split in 1978 into three separate journals. It was renamed as Journal of Chemical Sciences in 2004. The journal publishes original research articles and rapid communications, covering all areas of chemical sciences. A significant feature of the journal is its special issues, brought out from time to time, devoted to conference symposia/proceedings in frontier areas of the subject, held not only in India but also in other countries.
